V8R Rear Two Piece Brake Kit

SKU: N/A Categories: , ,


For the rear axle application, we’ve worked directly with StopTech and engineered the lightweight STR-21 caliper over both the sport and non-sport rotor. The STR21 was designed to be used for the rear axle that requires less pad volume than the STR-22 and non-vented, solid rotors. This package can be implemented in smaller wheel diameters, typical of most front-wheel drive race cars. Even with its smaller size, the STR-21 maintains caliper stiffness and optimal pad wear to provide the best performance in its class.

What’s Included

  • StopTech STR21 V8R Miata specific
  • 6061 brackets with 10.9 hardware
  • DOT approved stainless steel MX5 brake lines
  • Removes up to 7lbs per corner

Save an additional 2 lbs per corner on your NA or NB Miata by adding our optional two-piece rear hats brake kit upgrade.

    Installed on my Supercharged 94 – love that it uses the Stock Sport rotor and opens up all these race pad options. Super easy install and really like the quality on all the parts provided with the kit.
